501 Lens holder for later Gehmann irises
- 23mm lens holder allows a prescription
lens to be fitted eye-side of your rearsight manufactured exclusively
for our own latest irises with a detachable front thread and not
carrying our 1.5x magnified diopter

- 501, now with your iris mounted, is screwed into your rearsight after loosening the rail carrier's allen screw
- Mount your prescription lens in the lens holder which may be slid off the rail for easier assembly
- Reposition the lens holder on the rail as required and lock it in place
- Positioning
of the assembly on your rearsight is easily set as the attachment boss
has radial adjustment and is simply secured with the allen screw located
in the front body
